[C320-list] Leak on New 320 Mk11.

[VYC]

Hi all,
I have had a water leak appearing in the bilge since new on hull no.1162.
It appears to be salt water and appears even when the boat has been tied up
at the marina for a few days with no rain. (definitely not rain water)
Have put food dye in both water tanks , and water in the bilge is clear so
have eliminated fresh water.
The water is first spotted under  the aft. floor  section where the water
tank valves are located .It then appears to make its way to the 2 forward
sections of the bilge.
Initially after 3-5 days it used to only cover the keel bolts but recently
has got worse ,now covers 90% of bilge height after 1 week.
Have had to turn on auto bilge pump.
Water also comes in with sea cocks off. (except engine)
Cant see a water path from engine bay or stern land to that section where
the water appears.
The Catalina Agent has had a couple of shipwrights have a look ,and they
fixed other leaks which were there( rainwater  related),but this main leak
is still there.
It has been 12 months now and am seriously considering asking Catalina to
take the boat back if they cannot find/fix the leak.

Anyone got any ideas?

Best Regards
